Would it be possible to build a simple programmer based around this USB-Serial module?

http://www.ftdichip.com/Products/EvaluationKits/UM232R.htm

I need to program an ATtiny chip for a project I'm working on and was wondering if this might work for that purpose.

If so, what would I need to consider in order to connect the two?

Thanks!

yes you may search for `avrusb500` programmer in google.

it's a project on tuxgraphics.

The most(est) best(erest) thing with this programmer is that solves the chicken-egg issue, it programs the atmega8 (programmer mcu) through usb so you don't need a programmer actually in the first place.

and most(erest) best(erest) does not use the linked converter but tha FT232BL or BM tranceiver making it cheeper to assembly.

and most(erest) best(erest) is self powered from usb

i built one and fried my ft232bl smd before testing it but it probably works, my linux kernel loaded the usb2serial module when connected it

also is stk500v2 compatible and supported by avrdude and all the standard programmers. the cost for me to build it was 3 (pcb) + 5 (ft232bl) + 3 (atmega8) + 2 (all the rest) = 13 euro

Try http://www.matwei.de/doku.php?id=en:electronics:usbisp

I've built it myself, and it works great.

Thanks so much, everyone. Nice to have multiple options to examine.

Grab a Butterfly, and whack ButtLoad on it. Works great through the USB-RS232 FDTI bridge - Nard even made a complete package on his website here which you can use to customize it to show up as a "ButtLoad AVR Programmer" when plugged in. Since the Butterfly has its own Bootloader as well, there's no chicken-and-egg problem, or much wiring (none, if programming 3V parts) to do.

Butterflies are just getting back into stock, US$20 each.

This USB programmer is 28$
That includes delivery.
I'm not familiar with it
it's just the cheapest one
that a google search turned up.

Loks like a Mega8/48/88 to me , and it even has a 12Mhz Xtal on
it ... (Thats what is required for making USB on a Mega)

Hi guys..
The problem with this usb programmers are the speed. I made a programmer with FT232BM using ponyprog and it works but it is too slow. So i still keep with my serial programmer.

What about others USB programmer, how they are, fast? Like the ICprog-AVR2.0, is it fast?
